ROOFING OR SHEATHING.

SPECIFICATION forming part of Letters Patent No. 408,066, dated J uly30, 1889.

Application filed February 16, 1839. Serial No. 800,156. (No model.)

T0 (0% whom it may concern.-

Be it known that I, JOHN XV. BEAUMONT, a citizen of the United States,residing at Birmingham, in the county of Jefferson and State of Alabama,have invented new and useful Improvements in Roofing and Sheathing, ofwhich the following is a specification.

My invention relates to that class of building material. employed forroofing, sheathing, and other purposes; and the object thereof is toprovide asimple and inexpensive construction whereby the penetration ofwater at the joints between the several sect-ions shall be prevented andthe roofing rendered practically impermeable without the employment ofextraneous covering or other means of protection. It is my purpose toaccomplish this result by so constructing the mortise-joint between theadjacent roofing sections or strips that a secret channel or channelsshall be provided whereby the rain or other moisture penetrating saidjoint shall be carried off and discharged at the edge of the roofinstead of passing through the latter, whereby I am able to provide aperfectly water-tight roof without metal or other covering, or toprovide a sheathing which shall be free from leakage which results froman imperfect me tallic roof or from breaks occurring therein.

The invention consists in the several novel features of construction andnew combinations of parts hereinafter fully set forth, and thendefinitely pointed out in the claims following this specification.

Referring to the accompanying drawings, Figure l is a vertical sectionof a portion of roof or sheathing constructed according to my invention.Fig. 2 isaperspectivc view of one of the sections of sheathing'orroofing. Fig. 3 is a sectional view showing a modified construction.

In the said drawings, the reference-nu meral 1 denotes the roof or othersimilar structure, composed of similar strips or sections 2, constructedof wood, metal, or othersuitablematerial. These strips are connected attheir adjacent edges by a tongue or groove or mortise-joint consistingof a tenon or tongue 3011 one entering a groove or mortise 4, in theother. By the construction shown the tongue or tenon 3 has a slightinclination upward,

while the groove or mortise I has a corresponding inclination downward,whereby the angle between the upper surface of said tongue and the edgeof the strip 2 is less than a right angle. In this angle I form achannel or groove 5 by cutting away a portion of the vertical face oredge of the strip above the tongue or tenon 3, thus forming a gutter orpassage which is wholly in closed between the meeting edges of thestrips or sections of roofing. The inclined upper surface of the tongueor tenon lying directly beneath the narrow opening 6, between themeeting edges of the strips, any water from rain or melting snow whichenters through said opening will flow at once into the gutter or channel5, in which it will run, owing to the inclination of the roof, where itwill be discharged into the usual drip-trough or eaves-trough.

I may form a second channel or gutter 7 in the adjacent strip or sectionin the lower angle of the mortise or groove at, which will receive andcarry off any overflow from the channel 5 caused by an excess of waterentering through the opening 6.

I may cut the channel 5 partly in the upper surface of the tongue ortenon 3 and partly in the vertical edge of the strip above the tongue,and in like manner I may cut the channel 7 whollyin the lower inclinedface 4 of the groove 4, or partly in said face and partly in theadjacent face A.

The upper or exposedfaces of the strips 2 may be grooved or fluted toform longitudinal channels 8, by which the water will be carried off.

By this invention an extremely simple and inexpensive construction isprovided,whereby the roof is rendered practically water-tight. As theconcealed channel or channels between the adjacent strips giveaccommodation to and carry off any Water entering at the joint, it isnot necessary to pack the joint or to use any extraneous coveringtherefor. For light structures and for awnings, verandas, and similarparts, the invention affords a roofing which is practically imperviousand which may be used without metal or other covering. For sheet metaland other roofs, also, it provides a sheathing which is secured againstthe liability to leakage often caused by imperfect workmanship or by thebreaking or disintegration of the metal produced by oxidation or byfrequent strain.

Having thus described my invention, what I nel cut at the angle betweenthe tongue andthe edge from which it projects, substantially asdescribed.

2. A roofing or sheathing composed of similarstrips,each havingatongueproj ecting from one edge with an upward inclination, and agroove formed in the other edge, having a corresponding downwardinclination, said tongue and groove being intermediate of and at adistance from the two faces of the strips, a concealed channel or gutterbeing formed in the strip at the angle between the inclining uppersurface of the tongue and the edge from which it projects, substantiallyas described.

3. The combination, with a strip of roofing or sheathing having a tongueor tenon projecting with an upward inclination from one edge andprovided with a channel formed at the angle between the upper surface ofthe tongue and the edge of the strip, of a similar strip provided with agroove or mortise having a suitable inclination to receive said tenonand provided with a channel formed at the lower angle of the mortise orgroove, substantially as described.

In testimony whereof I have aflixed my signature in presence of twowitnesses.

JOHN WV. BEAUMONT.
